As announced on https://blog.linuxmint.com/, mint is porting the documentation to a new service : readthedocs.org
This is supposed to also ease the translation effort. I dont know any detail how, maybe someone of the team can give more info.
So I'm guessing it's better to wait till the new system is launched.

Hello,
I wanted to help translating user guides to italian.
Is there a mailing list for (italian) translators?
Is there kind of an organized group with rules to follow?
As member of the libreoffice l10n group, I use omegat (also in collaborative mode on github), so I thought maybe this way of translating could be useful for current and future documentation (of course not only for italian).
Any suggestion?
Thank you
